Abstract

The invention discloses a light guide structure of a lamp. The light guide structure of the lamp comprises a light guide, a condenser lens, a circuit board and LED lamp beads, wherein the back side ofthe light guide is a sawtooth face; the condenser lens is arranged at the first end of the light guide, and a groove is formed in the condenser lens; and the LED lamp beads are mounted on the circuitboard through a circuit and stretch into the groove. The side face of the outer end of the condenser lens can be a parabolic face or an ellipsoidal face, so that the light energy utilization rate ishigh, and the light emergence face is prevented from being granular and nonuninform.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a light guide structure of a lamp. Background technique [0002] With the continuous development of social economy, automobiles have become an essential travel tool for every household. Consumers not only put forward higher requirements for the comfort of the car, but also put forward more detailed requirements for the craftsmanship and appearance of the car. [0003] The lamps and lanterns of automobiles are described as the eyes of the car, and the cost of lamps and lanterns accounts for a large proportion of the cost of the whole vehicle. [0004] Consumers have higher requirements for the shape of lamps, and the structure and light distribution of lamps are more complicated. After the automotive lamps have experienced halogen and xenon, LED lamps, which were previously only used in high-end models, have also been accepted by more and more mid-range models. ...
